This is not called Multi-Region here but region free. I believe Mexico bans such players so you don't find them in most retail stores. As such you'll have to deal with off beat channels.
HELLO, I LIVE IN MEXICO CITY,MEXICO,AND I HAVE A FEW BLU-RAYS FROM REGION B2 ,FROM LONDON. HERE THEY CLAIM THAT I CAN BUY UPGRADED PLAYERS THAT WILL PLAY ALL BLU-RAY REGIONS. I IMAGINE THESE ARE NOT SANCTIONED BY SAY SONY OR SAMSUNG OR PANASONIC? OR CAN I TRUST THE SELLERS AND REALLY HAVE A REGION FREE PALYER. DO YOU KNOW ABOUT THIS? AND DO YOU HAVE ANY IDEAS OR RECOMENDATIONS? GHANK YOU, ALLAN ROTHMAN
